\section{\class{wxBufferedInputStream}}\label{wxbufferedinputstream}

This stream acts as a cache. It caches the bytes read from the specified
input stream (See \helpref{wxFilterInputStream}{wxfilterinputstream}).
It uses wxStreamBuffer and sets the default in-buffer size to 1024 bytes.
This class may not be used without some other stream to read the data
from (such as a file stream or a memory stream).

\section{\class{wxBufferedOutputStream}}\label{wxbufferedoutputstream}

This stream acts as a cache. It caches the bytes to be written to the specified
output stream (See \helpref{wxFilterOutputStream}{wxfilteroutputstream}). The
data is only written when the cache is full, when the buffered stream is
destroyed or when calling SeekO().

This class may not be used without some other stream to write the data
to (such as a file stream or a memory stream).

\membersection{wxBufferedOutputStream::wxBufferedOutputStream}

\func{}{wxBufferedOutputStream}{\param{const wxOutputStream\&}{ parent}}

Creates a buffered stream using a buffer of a default size of 1024 bytes for cashing
the stream {\it parent}.

\membersection{wxBufferedOutputStream::\destruct{wxBufferedOutputStream}}

\func{}{\destruct{wxBufferedOutputStream}}{\void}

Destructor. Calls Sync() and destroys the internal buffer.

\membersection{wxBufferedOutputStream::SeekO}

\func{off\_t}{SeekO}{\param{off\_t}{ pos}, \param{wxSeekMode}{ mode}}

Calls Sync() and changes the stream position.

\membersection{wxBufferedOutputStream::Sync}

\func{void}{Sync}{\void}

Flushes the buffer and calls Sync() on the parent stream.
